Does anyone know how a Crossfire owner with GPS Navigation will know when new CD's are issued? NAVTECH (now NAVTEQ) states that they update their United States database quarterly. Chrysler accesses the NAVTEQ database "at least once a year" but produces their own CD's. (At NAVTEQ's website you can buy other car manufacturer's updated CD's every 6 months, but NOT Chrysler's.) My Chrysler Parts Manager says that he will never know when new ones are available unless he has a part number. Since Chrysler doesn't issue part numbers sequentially for updates according to him, he says he will never know when an update is available. Also, Chrysler Tech Authority doesn't show the Navigation CD's among their manual listings. Chrysler Customer Service is totally worthless in my opinion!
